/* ** ** Swift/XRT hardness ratio for PKS 2155-304. ** Hardness ratio for this file has been calculated by splitting the data at 2.0 keV. ** ** Data taken from the automatic processing at http://www.swift.psu.edu/monitoring/ ** ** When using these data and results in publications, please reference M.C. Stroh & A.D. Falcone 2013, ApJS, 207, 28; arXiv: 1305.4949. ** ** Key: ** ** BinCenter - Center of time bin (MJD). ** BinHW - One-half of the full time bin size (days). ** FracExp - Conversion factor between bin size and observing time. ** Ratio - Source hardness ratio (2.0 - 10.0 keV)/(0.3 - 2.0 keV). ** This is also Rate2/Rate1 from the following columns. ** RatioError - 1 sigma error in the hardness ratio. ** Mode - 0 if in Windowed Timing (WT). ** 1 if in Photon Counting (PC). ** Rate1 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 0.3 - 2.0 keV band. ** RateError1 - 1 sigma error in source count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetRate1 - Background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetError1 - Error in the background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** Rate2 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 2.0 - 10.0 keV band. ** RateError2 - 1 sigma error in source count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetRate2 - Background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetError2 - Error in the background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** ** ** Upper limits have an error listed as -1.00000. ** */ BinCenter BinHW Ratio RatioError FracExp Mode Rate1 RateError1 NetRate1 NetError1 Rate1 RateError2 NetRate2 NetError2 56833.141942 0.000367 0.17923 0.04360 0.99213 0 2.05539 0.19688 1.77375 0.16988 0.36838 0.08238 0.31799 0.07110 56833.142980 0.000671 0.08688 0.02059 0.99569 0 2.26972 0.15442 1.97054 0.13406 0.19719 0.04476 0.17115 0.03885 56833.144335 0.000683 0.09298 0.02207 0.97458 0 2.12836 0.14743 1.84878 0.12806 0.19790 0.04492 0.17189 0.03902 56833.145648 0.000631 0.09928 0.02329 0.97248 0 2.19418 0.15538 1.90326 0.13478 0.21784 0.04871 0.18899 0.04226 56833.147029 0.000749 0.09198 0.02099 0.97297 0 2.09295 0.13952 1.81532 0.12101 0.19251 0.04201 0.16694 0.03643 56833.148090 0.000312 0.19514 0.04846 0.96296 0 2.27247 0.22817 1.94897 0.19567 0.44345 0.10071 0.38015 0.08630 56833.148880 0.000477 0.13526 0.03273 0.98182 0 2.08865 0.17489 1.80070 0.15076 0.28251 0.06413 0.24405 0.05540 56833.149899 0.000541 0.12142 0.02916 0.97326 0 2.07064 0.16248 1.79004 0.14046 0.25142 0.05707 0.21723 0.04931 56833.150943 0.000503 0.15750 0.03791 0.96552 0 1.76708 0.15728 1.51876 0.13517 0.27831 0.06224 0.23849 0.05333 56833.152092 0.000645 0.13935 0.02770 0.97309 0 2.25571 0.15602 1.95141 0.13497 0.31433 0.05857 0.27206 0.05068
